In addition to this, the PCIe card installation manual says in Windows 7, it'll be listed under the "IDE ATA/ATAPI controller" category as "Standard AHCI device". As you can see, it doesn't mention Standard AHCI device.

How to get this working?

EDIT: I forgot to add - when i booted into Windows, it just said it needed to be restarted, but this didn't fix the problem.
